What should I pay attention to when cleaning the accelerator?

There are two kinds of cleaning methods. One is to remove the throttle assembly, and the technicians use special cleaning agent to clean the pollutants inside the throttle, and then install and restore it, so that the cleaning effect is more thorough. There is another way, that is, when the engine is running, the cleaning agent is continuously sprayed through the "hanging bottle" in the engine intake. Although this cleaning takes a long time, it is simple to operate.

After taking out the throttle, you can find a lot of oil stains inside and outside the throttle, and a lot of dirt and impurities are attached. After spraying detergent on the dirty part, you can wipe it carefully with a cloth. Don't be lazy when wiping, especially pay attention to those cracks that are easy to hide evil and shelter evil. If the gap is too small, you can clean it with a cotton swab dipped in detergent. As long as we wipe it carefully, the throttle can be as clean as new. With a clean throttle, the car can "breathe" smoothly and freely.

Remove the throttle valve for cleaning. Although it's a little troublesome to operate by yourself, it's better to clean it thoroughly. Generally speaking, 4S stores will not remove the throttle separately for cleaning. They just step on the accelerator and open it before cleaning, so it is difficult to clean it thoroughly, and there is a risk that foreign objects will fall in.

After cleaning the throttle, we must match the throttle data with the detection computer and reset the throttle opening, because the ECU (driving computer) of the car has memorized the opening when there is carbon deposit. If it is not reset, the engine will have unstable idle speed and high speed, which is even worse than before cleaning, so the owner had better not wash the throttle himself, and this part of the money can't be saved. After all, data matching can only be done with professional equipment.
